BACKGROUND Technical Field

The present technology relates to a sausage package dispensing system, device and method for use in connection with controllably dispensing material from a chub or sausage package and more specifically to methods and apparatuses related to hand-held caulking guns that can pierce the sausage package. The present technology can further relate to an adapter system for use in connection with a dispensing device for dispensing material from the sausage package.

Background Description

Material dispensing systems are desirable for providing an ergonomic hand-held device controllably dispensing a material with a desired bead size and shape. The use of caulking or sealing materials to fill gaps between constructions is known. The caulking materials can be utilized indoors and outdoors, and can further be paintable to seamlessly blend between the constructions. There are many different types of caulking materials, along with different types of systems to dispense them.

Squeezable packaging with a nozzle top can be employed to store and then dispense the caulking material. These types of packaging's typically hold a small amount of material, and controlling the dispensing of the material can be difficult.

Hand-held material dispensing devices, such as caulking guns, are well known and generally rely on the action of a piston to push caulk material out of a caulk tube. The motion of the piston is induced by the advancement of a piston rod in the direction of the caulk tube, with the piston rod being advanced in the direction of travel by the operator's squeezing of a trigger.

These known devices are designed to receive and carry a disposable caulk tube. The housing of these caulking guns and the trigger are generally formed of stamped metal plate for manufacturing economy. The caulk tube generally includes a rigid cylindrical tube featuring a sliding piston (plunger), and a nozzle tip, with material stored inside the tube. The caulk tube is commonly more expensive to manufacture than a sausage package because of the different structural elements. While a sausage package is considerably less expensive and easier to manufacture since it is a type of container formed by a tube of flexible packaging material crimped at the ends after filling.

To overcome the disadvantages of caulking tubes, manufacturers developed so called “sausage package” or “chub packs” for the sealant compositions. Sausage packages use less material for the manufacture of the package as compared to caulking tubes, and can be made to be impermeable to air and moisture. They also take up less space in the case package. This allows for a sealant composition stored therein to maintain its consistency and useability and reduce curing of the material. Overall this leads to less waste in both packaging and in preservation of the product in the packaging.

While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned devices or systems do not describe a sausage package dispensing system that allows controllably dispensing material from a sausage package.

A need exists for a new and novel sausage package dispensing system that can be used for controllably dispensing material from a sausage package. In this regard, the present technology substantially fulfills this need. In this respect, the sausage package dispensing system according to the present technology substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of controllably dispensing material from a sausage package.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc. in order to provide a thorough understanding of the present technology. However, it will be apparent to one skilled in the art that the present technology may be practiced in other embodiments that depart from these specific details.

Referring now to the drawings, and particularly to FIGS. 1-17 , an embodiment of the sausage package dispensing system, device and method of the present technology is shown and generally designated by the reference numeral 10.

In FIGS. 1 and 2 , a new and novel sausage package dispensing system or device 10 of the present technology for controllably dispensing material from a collapsible package or sausage package 2 is illustrated and will be described. More particularly, the sausage package dispensing system 10 can be associated with a sausage dispensing device 12 configured to receive a collapsible package or sausage package 2, a package tube 28, a piercing nozzle 30, 80, and a plunger 140. The package tube 28, the piercing nozzle 30, 80, and the plunger 140 can be provided together as an adapter system to the dispensing device 12, or can be provided separately, or can be provided with the dispensing device 12 as a single unit.

It can be appreciated that the sausage package 2 can include any cylindrically-shaped or sausage-shaped casing package that is collapsible and contains an extrudable material therein. In the exemplary the extrudable material can be, but not limited to, a sealant, grease, a lubricant, food materials, a caulking, a paste, mixable compounds, a filler and the like.

Many advantages come with packaging adhesive and sealant products in the sausage package 2. A first advantage is that the sausage package 2 itself represents an initial cost savings compared to a conventional cartridge or tubes in manufacturing. As the cost in manufacturing the sausage package is substantially less than manufacturing a conventional cartridge or tube.

Another advantage is the extended shelf life of the material in the sausage package 2. Sausage packaging uses a flat film that is then formed into a sausage and clipped or sealed with product material stored therein. As a result, no air is introduced during the filling process. The film used to form the sausage package 2 also provides an excellent moisture barrier, such as multi-layered film with a trapped aluminum.

Still another advantage is the increased space savings for storing in warehouses, on store shelves, during transportation or carrying by a user to a job site or location.

Another key benefit of the sausage package 2 is lower disposal costs. Since an empty sausage package is basically a small, compressed, foil disc that is 10% the size of a typical empty cartridge or tube, disposal cost savings can be high. In addition, the sausage package 2 can result in less waste going to the landfill, which is a key component in environmental sustainability.

The present technology provides efficient dispensing of the material in the sausage package 2 by utilizing aftermarket components that can be easily used with existing caulking guns or can be an all in one caulking gun or dispensing device including the components of the present technology.

For exemplary purposes, the sausage dispensing device 12 can have a configuration similar to a gun featuring a main housing 14, a plunger rod 16, an internal cavity featuring reinforcing ribs 18, and a dispensing end section 20. A hand grip, a trigger and a piston grip can be utilized with the dispensing device 12. It can be appreciated that the plunger rod 16 of the dispensing device 12 can be manually driven via a rack or ratcheting system or via a motor and gear system. The main housing 14 can be made of, but not limited to, plastic, metal, composite, an alloy or any combination thereof. The dispensing device 12 can be a single molded unit or can be made of separable and attachable sections secured together by, but not limited to, adhesive, welding, fasteners, tabs, locks, clips or other securing means.

The internal cavity of the main housing 14 can be configured to receive the sausage package 2 directly or receive the package tube 28 with the sausage package 2 located inside the package tube 28. Reinforcing ribs 18 can be configured to provide rigidity to the dispensing device 12, to support the package tube 28 received in the main housing 14 and/or to assisting in containing or guiding the sausage package 2 while contained in the internal cavity.

The package tube 28 can be a hollow tube with opposite open ends thereby allowing reception of the sausage package 2 inside the package tube 28 from either end. A width or diameter of the package tube 28 can be sized to be received in a caulking gun or the internal cavity of the main housing 14 of the dispensing device 12. The package tube 28 can be made out of any suitable material such as, but not limited to, plastic, metal, alloys, cardboard and the like. Further, the package tube 28 can be transparent or include a window or opening to easily view the sausage package 2 inside the package tube 28. It can be appreciated that the package tube 28 can include ribs or grooves to increase rigidity of the package tube 28 and/or to prevent bending or expansion of the package tube 28 during use.

The plunger 140 can be configured to be attachable to the plunger rod 16 or a part associated therewith, and can be further configured to be slidably raceable within the package tube 28. Alternatively, the plunger 140 can be configured to be slidably receivable along a longitudinal axis of the internal cavity of the main housing 14 so that it can be used without the package tube 28.

The dispensing end section 20 can be configured to receive the piercing nozzle 30, 80 therein so that at a male portion 70, 130 of the piercing nozzle 30, 80 can be inserted through a dispensing end opening 22 defined through the dispensing end section 20 of the dispensing device 12.

A nozzle tip 160 can be attachable to the male portion 70, 130 of the piercing nozzle 30, 80 thereby securing the piercing nozzle 30, 80 to the dispensing end section 20, as best illustrated in FIG. 2 . The nozzle tip 160 can be configured to assist in dispensing and/or spreading material dispensed from the sausage package 2 onto a surface or into a gap. The nozzle tip 160 can be made of, but not limited to, plastic, metal, composite, an alloy or any combination thereof.

With reference to FIGS. 3-7 , an embodiment of the piercing nozzle 30 is illustrated and will be described. The piercing nozzle 30 can be removably attachable to or integrally formed with the dispensing end section 20. The piercing nozzle 30 can include a housing featuring a nozzle sidewall 32 defining a nozzle cavity 34 therein configured to receive an end of the sausage package 2. The piercing nozzle 30 can be made of, but not limited to, plastic, metal, composite, an alloy or any combination thereof.

A width or diameter of the sidewall 32 can be substantially the same as the width or diameter of the package tube 28, so that they contact each other during use and allowing the end of the sausage package 2 to easily travel through the open end of the package tube 28 and into the nozzle cavity 34. Alternatively, the width or diameter of the sidewall 32 can be greater than the width or diameter of the package tube 28 thereby allowing either end of the package tube 28 to be received in the nozzle cavity 34. In another alternative, the width or diameter of the sidewall 32 can be less than the width or diameter of the package tube 28 thereby allowing the sidewall 32 portion of the piercing nozzle 30 to be received in at least a portion of the hollow interior of the package tube 28.

A ledge 36 can extending from a perimeter of the nozzle sidewall 32 at a location where the nozzle sidewall 32 transitions to a nozzle end wall 38. The ledge 36 can have a width or diameter greater than nozzle sidewall 32. The ledge 36 can be configured to prevent the piercing nozzle 30 from being completely inserted into the hollow interior of the package tube 28.

An angled or curved section 40 can transition from the ledge 36 to the nozzle end wall 38. The section 40 can be indented toward the nozzle cavity 34, thereby creating a recessed space in relation to the ledge 36 and the nozzle end wall 38. A nozzle opening 41 can be centrally defined through the nozzle end wall 38 and configured to allow material from the sausage package 2 to pass therethrough.

The male portion 70 can extend from the nozzle end wall 38 in a direction away from the nozzle sidewall 32. The male portion 70 can defined a longitudinal male portion bore 72 therethrough, and can include external threads 74. The male portion bore 72 is in direct fluid communication with the nozzle opening 41, thereby allowing material from the sausage package 2 to be received from the nozzle opening 41 and exit the male portion 70. Further, the male portion bore 72 can convergingly taper in a direction toward the nozzle end wall 38 so that a first width or diameter of the male portion bore 72 adjacent the nozzle opening 41 is less than a second width or diameter of an exit end of the male portion bore 72 opposite the nozzle opening 41.

It can be appreciated that the male portion 70 can be integrally formed with and extending out from the dispensing end section 20.

A width or diameter of the male portion 70 including the external threads 74 can be configured to be inserted through the dispensing end opening 22, as best illustrated in FIG. 7 . It can be appreciated that the dispensing end opening 22 is configured to prevent the housing of the piercing nozzle 30 from passing therethrough. When the piercing nozzle 30 is assembled in the dispensing end section 20, the ledge 36 and/or the nozzle end wall 38 can abut or contact an end wall of the dispensing end section 20 that includes the dispensing end opening 22.

The nozzle tip 160 can include an attachment end configured to secure the nozzle tip 160 to the male portion 70. This can be accomplished, but not limited to, by utilizing internal threads of the nozzle tip 160 that are engageable with the external threads 74 of the male portion 70. It can be appreciated that other securing mechanisms can be utilized instead of threads such as, but not limited to, ratchets, clips, latches, locks or magnets.
